At least 20 dead, 100 injured in Las Vegas Strip shooting

LAS VEGAS (AP) — At least 20 people were killed and 100 wounded during a shooting at an outdoor music festival on the Las Vegas Strip late Sunday.

Dozens of patrol vehicles descended on the Strip after authorities received reports of an active shooter near the Route 91 Harvest Festival. Las Vegas police later said one suspect was "down" and they did not believe there were any other shooters.

Concert-goers reported seeing muzzle flashes from the upper floors of the Mandalay Bay Hotel and Casino across Las Vegas Boulevard from the country music festival and the sound of what they described as automatic gunfire.

Kodiak Yazzie, 36, said he and his girlfriend were watching Jason Aldean's performance when he heard what sounded like fireworks. The music stopped temporarily and started up again before another round of pops sent the performers ducking for cover and fleeing the stage.

Thousands fled as bursts of gunfire could be heard for more than five minutes, Yazzie said.

Witnesses said they saw multiple victims and dozens of ambulances near the concert venue. Some attendees later huddled in the basement of the nearby Tropicana hotel-casino.

Flights were temporarily halted at McCarran International Airport because of the shooting, the airport said on its verified Twitter account.
